Abstract

PURPOSE: To fix moving vanes without generating the concentration of stress, by each mounting grooves forming holes for instaling stoppers at locations where the root portions of a moving vane lastly studded and a neighboring moving vane mutually face, and by inserting stoppers into the grooves.
CONSTITUTION: Grooves 16, 16' with the same shapes for forming holes for installing stoppers are each mounted at locations where a root portion 3 of a moving vane 3' lastly studded and the root portions of moving vanes 3, 3 next to the moving 3' mutually face. The grooves 16, 16' are formed in semicircular large diameter portins 16a and small diameter portions 16a and small diameter portions 16b extending up to the outsides of the root portions 3b. Stoppers 17 are shaped by large diameter portions 17a and small diameter portions 17b, which sections are the same circles as the installing holes, and divided into two portions at the centers. Thus, the one sides of the stoppers 17 are installed to the grooves 16, 16' of the moving vanes 3, 3', the moving vane 3' is studded to a groove of an outer circumference of a rotor from the axial direction, the stoppers 17 are fixed in the axial direction by turning the stoppers at an angle of 90° and the small diameter portions 17b are caulked.
